Abstract

L'invention concerne un dispositif de commande utilisé pour des turbocompresseurs multi-étages d'un moteur, ce qui améliore la consommation de carburant lors des modes transitoires et statiques du moteur. Le dispositif de commande (1) pour les turbocompresseurs multi-étages qui sont des turbocompresseurs (6, 7) comprenant au moins deux étages, est monté en série avec le moteur (2), le turbocompresseur (6) côté haute pression est un turbocompresseur de type à déplacement variable comprenant des lames variables (64). Le dispositif de commande (1) comprend des moyens de détection (11, 12) destinés à détecter la pression de suralimentation ou la quantité d'air d'entrée du turbocompresseur (7) sur le côté de l'étage basse pression du turbocompresseur (6) à déplacement variable. La commande d'ouverture des lames variables (64) est fondée sur des valeurs détectées par des moyens de détection (11, 12).
